Protect PDF

Encrypt a PDF with a password so only people you trust can open it.

How to use

  1. Drop in your PDF.
  2. Set a password (share it with recipients separately).
  3. Download the encrypted PDF - it now requires the password to open.

Frequently asked questions

The file is encrypted with standard PDF encryption supported by all major readers.

What if I forget the password?
